WebApr 16, 2024 · When the equality is fulfilled in Grashof's formula, then we are in the limiting case in which the sum of the shortest bar with the longest bars is equal to the sum of the other two. In this case, the mechanism can take a configuration in which the four bars are aligned. And it is in this position, the non-fixed joints can indifferently go one ... WebThe ratio Ra / Pr is also called the Grashof number Gr =α g Δ Tnaa3 /ν 2 (Grashof, 1826–1893). This number can also be written as V0a /ν and could be called the Reynolds number, Re, of the flow (Reynolds, 1842–1912). Using one or the other names depends on the quantities that are best known.
